Unlike other Afrikaans verbs, the past participle of wees (gewees) does not usually take the auxiliary verb het to form the perfect tense unless a modal verb is being used: Ek sou baie kwaad gewees het as jy dit gedoen het. (“I would have been very angry if you had done this.”) Outside of this construction, het gewees is rarely encountered and is considered nonstandard. The actual perfect tense of wees is is gewees, but this form is also very rare, being usually replaced with either was or was gewees. (The latter is formally a pluperfect, but is generally used without any semantic distinction.)
